WINDOW.

SPEGFICATION forming part of Letters Patent No. 664,993, dated January1, 1901.

Application filed April 2, 1900.

To @ZZ whom it may concern,.-

Beit known that I, CHARLES CHMELITZEK, a citizen of the United States,residing at New York city, county and State of New York, have inventedcertain new and useful Improvements in Windows, of which the followingis a specification.

My invention relates to an improvement in windows of the type whichconsist of a frame containing two vertically movable sashes and eachsash carrying an inner glass-holding swinging sash.

The novel features of invention consist:

First. In a locking device by reason of which the vertically-movablesashes may be locked against movement when their swinging sashes areopened, and, conversely, the swinging sashes may be locked when thevertically-moving sashes are movable, the object of this arrangementbeing, irst, to prevent injury to the glass in the swinging sashes,which is apt to occur by the sudden movement upward of thevertically-movable sashes when the swinging sashes are opened to theirfull extent, it being understood that when the swinging sashes areopened to nearly their full extent the weight of the swingingsash-frames and their contained glass will n0 longer resist theinfluence of the sash-weights tending to move upward thevertically-movable sashes, and, second, to prevent injury to the sashesby one part striking another, which is apt to occur if the swingingsashes are not firmly locked in their closed positionbefore thevertically-movable sashes are moved.

Second. In the employment Vin connection with the swinging sashes ofdevices normally out of sight and use, which when connected with theswinging sashes will limit their movement and prevent injury to them.

Third. In the use in connection with the swinging sashes of deviceswhich will liniit the movement ofthe swinging sashes and which may bereadily detached when a movement greaterthan that permitted by suchdevices is required.

The accompanying drawings will serve to illustrate my invention.

Figure 1 is a view in perspective of a window-frame, showing bothswinging sashes opened and with the lower vertically-mov- Serial No.11,271. (No model.)

able sash in its upper position and the upper movable sash in its lowestposition. At the left of this iigure the frame is broken away to showthe arrangement of adjustable 55V weights connected to theretaining-cords for the swinging sashes. Fig. 2 is a section v throughthe window-frame and one set of sashes, illustrating the vposition andrelation of the locking device to the frame and sashes. 6o Fig. 3` is asection taken on the line X X of Fig. 2 looking upward. Fig. 4 is atransverse section on the line Y Y of Fig. 2. Fig.

5 is a transverse section through thelneeting-rails of the upper andlower vertically- 65 movable sashes, with their contained swingingsashes, with the window closed, the sec- -tion being taken through themiddle of the sashes at the point where the spring-catch is located.Fig. 6 is a front view of the catch- 7o plate. Fig. 7 is a section ofthe catch-plate and limitingstrap.- This view shows' the limiting-strapabout to be introduced and secured in theV catch-plate.

In the drawings similar numerals indicate 75 like parts throughout theseveral gures.

In the drawings, l0 represents a windowframe, which is of the ordinaryconstruction. Located-within the window-frame and adapted to be moved bythe ordinary cords and weights 8o are the vertically-movable sashes 1llli. Y Situated within these sashes are the swinging sashes l2 12a. Theswinging sashes are hinged at the bottom to the vertically movablesashes. Normally the swinging sashes 12 l2fJL 85 are held closed withinthe vertically-movable sashes by means of the spring-catches 13.

In Fig. 5 I have shown the construction of the joint between the frameof the upper ver,- tically-movable sash and its contained swingl9o ingsash, by reason of which the sash is made both wind and rain proof.

The swinging sash 12a is hinged, as shown at 14, to thevertically-movable sash 11', and the under surface 12b of the lower railof the 95 swinging sash'12a is so formed as to overlap both the upperand outer surfaces 11b of the lower rail of the vertically-movable sash11. This is accomplished by giving the meeting faces of the two sashesan inclination downroo ward from within outward and providing the lowerrail of the swinging sash 12a with the depending portion 12u. I alsoconstruct the meeting faces of the swinging sash and vertically-movablesash in a similar manner.

Located on the top and on opposite sides of the top rail of thevertically-movable sashes 1l 11 are the double-action locks 15. Theselocks are countersunk in the top of the rail and consist, essentially,of a top plate 16, Fig. 3, carrying the studs 17, which support a plate18, slotted at 19 and carrying the depending hook 20 and bolt 21.Movement is imparted to the plate 18 and through it to hook 20 and bolt21 by means of a thumbpiece 22, which projects upward through a slot(not shown) in the plate 16. The hook portion 20 is adapted to takeunder a plate 23, countersunk in the top of the swinging sash 12. Thebolt 21 is adapted to be passed into an opening in the plate 24 in theside of the window-frame. The operation of this doubleacting bolt willbe readily understood.

I/Vhen the parts are in the position shown in Fig. 2, the swinging sash12 cannot be moved outward, as it is retained by the hook 20 takingunder the plate 23, but the vertical sash 11 is free to move upward.When the parts are in the position shown in Fig. 3, the swinging sash 12is free to move outward; but the vertical sash cannot be moved upward,as the bolt 2l takes into the plate 24. In order to support the swingingframes, I provide the retaining-cords 25. These cords are located withinthe window-frame, as at 26 26a, and are retained therein and travelthrough a plate 27. They consist of a cord 25, on one end of which arelocated a number of separate weights 28 and at the other a catch-pin 29,which is adapted to take in the socket 30 on the front of the swingingsash 12. Preferably the plates 27 on the windowframe are screwedinposition and ofa diameter sufficient when removed to permit the weights2S to be carried out of the opening in the window-frame for the purposeof adding a greater or less number of weights to the retaining-cord tocounterbalance the weight of the swinging frame.

For the purpose of normally limiting the outward movement of theswinging frames I provide the hinged strap 31. These straps are pivotedto the Window-frame by a plate, as at 32. The outer end of the strap 31is provided with a pin with enlarged head which projects inwardly. 33represents a plate countersunk in the said swinging sashes. At thebottom of the plate there is an opening 34- of the same diameter as thehead of the pin on the end of the strap, and carried upward from thisopening is a slot 35 of the diameter of the shank of the pin. Situatedbehind the slot 35 is a spring 36, which exerts outward pressure andwhich is turned backward at its upperend. It will be understood thatwhen the head of the pin is placed in the opening 34 and then pushedupward the spring is pushed back until the head of the pin passes thespring, when the spring moves outward and under the head, thuspreventing the head from moving down ward and holding the strap inposition. To release the swinging frame, the pin is moved downward inthe slot and then taken out of the catch.

A window constructed according to the foregoing description and as shownin the accompanying drawings may be readily cleaned with safety to theperson doing the work. It may also be adjusted in various positions, aswill be readily understood, in order to obtain effective ventilation.

Having thus described my invention, I claim- 1. In a window, thecombination of a frame, a vertically-movable sash, a swinging sashhinged to said vertically-movable sash, anda lock carried by saidvertically-movable sash, said lock consisting of a plate carrying a boltand a depending hook, said bolt adapted to coact with the window-frameand said hook with the swinging sash, whereby when the bolt coacts withthe frame, the swinging sash will be released, and when the hook coactswith the swinging frame, the vertically-movable sash will be free to bemoved.

2. Ina window, the combination of aframe, a vertically-movable sash, aswinging sash pivoted to the vertically-movable sash, anda retainingdevice for the swinging sash, comprising a weighted cord, the weights ofwhich are situated within the window-frame, and said cord provided witha catch-pin on its outer end adapted to coact with sockets on the facesof the swinging sashes.

In testimony whereof I affix my signature in the presence of twowitnesses.
